49.95 is what percent of 77.45 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 77.45 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 77.45, so we can write it down as 100%=77.45.
4. We know, that x% equals 49.95 of the output value, so we can write it down as x%=49.95.
5. Now we have two simple equations:
1) 100%=77.45
2) x%=49.95
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=77.45/49.95
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 49.95 is what percent of 77.45

100%/x%=77.45/49.95
(100/x)*x=(77.45/49.95)*x       - we multiply both sides of the equation by x
100=1.5505505505506*x       - we divide both sides of the equation by (1.5505505505506) to get x
100/1.5505505505506=x
64.493221433183=x
x=64.493221433183

now we have:
49.95 is 64.493221433183% of 77.45
